Do benthic diatom assemblages refl ect abiotic typology: a case study of Croatian streams and rivers
Benthic diatoms are widely used in Europe and worldwide to access ecological status of running waters. One of key goals of Water Framework Directive is to classify rivers and streams using biological quality elements and type specifi c reference conditions. According to system B which incorporates additional abiotic descriptors, there are 24 water types in Croatia. For biological analyses 92 ri...
متن کاملpatterns and variations in native and non-native interlanguage pragmatic rating: effects of rater training, intercultural proficiency, and self-assessment
although there are studies on pragmatic assessment, to date, literature has been almost silent about native and non-native english raters’ criteria for the assessment of efl learners’ pragmatic performance. focusing on this topic, this study pursued four purposes. the first one was to find criteria for rating the speech acts of apology and refusal in l2 by native and non-native english teachers...
15 صفحه اولPatterns of plant traits in Pyrenean alpine vegetation
Here we studied the adaptation of plant communities to environment in the alpine belt of the Catalan Pyrenees through comparative analysis of plant traits. The starting point consisted of about 800 phytocoenological relevés from the Banc de Dades de Biodiversitat de Catalunya, which corresponded to 47 communities (associations and subassociations) and included 683 taxa. Eleven attributes were e...

Impact of climate change on population dynamics and temporal patterns of benthic assemblages of rivers
Seasonal cycles of temperature, water regime and day length act as “Zeitgeber” (timer) triggering stage transitions in the life cycle of organisms provoking temporal patterns of communities at different levels of organization. Climate change is both affecting temperature forcings and water regime. Mathematical models are set up to investigate the mechanisms for the change of temporal patterns i...
